Abstract
Binge eating (BE) is consuming large amounts of food in a short time, while experiencing loss of control over eating behavior. BE can be hereditary, and juvenile stress (JS) may contribute to its onset. We examined the impact of JS on BE-like behavior, in an animal model of intergenerational BE. Twenty-four female Wistar rats received 2-h access to palatable food (PF) three or five times a week (3 TW or 5 TW) for 4 weeks, followed by the open field test (OFT). At postnatal day (PND)27-29, female offspring either underwent JS (O-JSC) or not (O-CC). At PND51-53, offspring's stress levels were assessed behaviorally. At PND70-85, offspring received 2-h access to PF three times a week to assess their BE-like tendency. Hair samples were collected afterwards. Compared to 5 TW, 3 TW had a greater binge size. In the elevated plus maze and dark\light box, in O-JSC, offspring of 3 TW (O-3TW) spent less time in the open arms and lit area compared to O-5TW. O-3TW consumed more PF than O-5TW. O-JSC consumed more than O-CC. O-3TW-JSC had higher hair CORT levels than O-3TW-CC and O-5TW-JSC. This study highlights the interplay between maternal and offspring experiences, allowing for the study of underlying mechanisms.

The different areas of chronic stress and food addiction: Results from the LIFE-Adult-Study. Stress Health 2024; 40:e3348.

Abstract
There is an empirical association between stress and symptoms of food addiction (FA), but it is still not clear which domains of stress are the most relevant when it comes to FA, limiting the ability of researchers and practitioners to address problematic eating-related health outcomes. In order to address this gap in the literature, we analysed how different domains of chronic stress are related to FA. We used data from a subsample of the LIFE-Adult-Study (N = 1172), a German cohort study. We conducted a linear regression analysis with stress domains (Trier Inventory for Chronic Stress, TICS) as predictors of FA (Yale Food Addiction Scale, YFAS). In the second regression analysis we included sociodemographic variables, personality, and smoking as control variables. There was a significant and positive association between Social Overload, Work Discontent, Excessive Demands from Work, and Chronic Worrying and FA. After adding control variables, only Social Overload, Excessive Demands from Work, and Chronic Worrying remained significant predictors. Connections between stress domains and FA can serve as starting points for the development of meaningful interventions that support individuals self-care strategies (Social Overload), complexity management (Excessive Demands from Work), and coping with negative emotions (Chronic Worrying).

Abstract
ISSUE ADDRESSED Nostalgia-the bittersweet reliving of the past-has been linked to social connection and psychological wellbeing. Although food consumption is often an intrinsically social experience, relatively little research has examined how individuals experience and understand how food consumption relates to feelings of nostalgia, food and mood. METHODS In the current study, semi-structured interviews were conducted with eight Australians from varying cultural backgrounds to explore their experiences with nostalgia, food and mood. RESULTS Reflexive thematic analysis identified three key themes from the data: (i) The bittersweet experiences of food-evoked nostalgia-individuals' descriptions of food-evoked nostalgia and how it impacted their mood both positively and negatively (ii) social connection and identity continuity-participants' description of food-evoked nostalgia and how this provides an opportunity for social connection and identity continuity throughout life, which positively influences mood, and (iii) the role and relationship of food-evoked nostalgia and mood-individual descriptions of the important role that nostalgic food plays in their life, in addition to their relationship with food, and how this impacts mood. CONCLUSIONS Understanding the positive component of nostalgic foods allowed individuals to bolster positive mood states with food-evoked nostalgia, increasing their quality of life. SO WHAT?: Understanding the link between food-evoked nostalgia and mood has significant implications, suggesting that negative mood states altered by nostalgic foods may result in positive mood states. Appropriate use of food-evoked nostalgia may increase the quality of life for individuals experiencing low mood states.

Characterization of adults concerning the use of a hypothetical mHealth application addressing stress-overeating: an online survey. BMC Public Health 2024; 24:958. [PMID: 38575925 PMCID: PMC10993539 DOI: 10.1186/s12889-024-18383-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2023] [Accepted: 03/18/2024] [Indexed: 04/06/2024] Open
Abstract
BACKGROUND About 40% of people respond to stress by consuming more unhealthy foods. This behavior is associated with increased energy intake and the risk of obesity. As mobile health (mHealth) applications (apps) have been shown to be an easy-to-use intervention tool, the characterization of potential app users is necessary to develop target group-specific apps and to increase adherence rates. METHODS This cross-sectional online survey was conducted in the spring of 2021 in Germany. Sociodemographic data and data on personality (Big Five Inventory, BFI-10), stress-eating (Salzburg Stress Eating Scale, SSES), and technology behavior (Personal Innovativeness in the Domain of Information Technology, PIIT; Technology Acceptance Model 3, TAM 3) were collected. RESULTS The analysis included 1228 participants (80.6% female, mean age: 31.4 ± 12.8 years, mean body mass index (BMI): 23.4 ± 4.3 kg/m2). Based on the TAM score, 33.3% (409/1228) of the participants had a high intention to use a hypothetical mHealth app to avoid stress-overeating. These persons are characterized by a higher BMI (24.02 ± 4.47 kg/m2, p < 0.001), by being stress-overeaters (217/409, 53.1%), by the personality trait "neuroticism" (p < 0.001), by having specific eating reasons (all p < 0.01), and by showing a higher willingness to adopt new technologies (p < 0.001). CONCLUSION This study suggests that individuals who are prone to stress-overeating are highly interested in adopting an mHealth app as support. Participants with a high intention to use an mHealth app seem to have a general affinity towards new technology (PIIT) and appear to be more insecure with conflicting motives regarding their diet. TRIAL REGISTRATION This survey was registered in the German Clinical Trials Register (Registration number: DRKS00023984).

Abstract
BACKGROUND Understanding how individuals currently perceive healthy eating is essential for developing food policies and dietary recommendations that improve the health and well-being of populations. The purpose of this qualitative evidence synthesis was to systematically outline the views and understandings of healthy eating, focusing on how foods are classified as healthy and unhealthy and what meanings are attached to food and eating by the general adult population in high-income countries. METHODS A systematic search of four electronic databases was conducted and yielded 24 relevant primary qualitative studies of generally healthy, community-dwelling adults. RESULTS Thematic synthesis of the included studies identified three analytic themes: constructions of healthy and unhealthy eating, considerations on dietary recommendations, and meanings attached to food and eating. Study participants generally understood what constitutes a healthy and unhealthy diet which was in line with dietary recommendations, but those of lower socioeconomic status exhibited gaps in nutrition knowledge. Participants expressed diverse opinions on dietary recommendations, including skepticism and a lack of trust. Food and eating were associated with various meanings, including pleasure, stress relief, and feelings of guilt. Moral, health, and sociocultural considerations also played a role in dietary behaviors. CONCLUSIONS The findings suggest that improving population diet requires considering how dietary recommendations are phrased and communicated to ensure that healthy eating is associated with pleasure and immediate well-being. This review provides valuable insights for developing consumer-oriented, practicable, and acceptable food policies and dietary recommendations that effectively improve population health and well-being.

Impact of hospitalisation on behavioural and physiological stress responses associated with cardiovascular risk in visiting family members. Aust Crit Care 2023; 36:762-768.

Abstract
BACKGROUND The hospitalisation of a patient in intensive care impacts the psychological health of family members, with a high prevalence of anxiety, depression, and post-traumatic stress symptoms reported among families of critically ill patients. Understanding of the behavioural and physiological impact is limited and presents a new area of focus. OBJECTIVES The objective of this study was to evaluate behavioural and physiological stress responses of visiting family members following hospitalisation of their adult relative. METHODS Prospective longitudinal evaluation included 40 family members of adult patients with admission to intensive or coronary care in a large tertiary care metropolitan hospital. Assessments were conducted at three timepoints: in-hospital within 1 week of admission and 2 weeks and 3 months post discharge. Assessments included duration and quality of sleep (self-reported and actigraphy measured), physical activity, dietary and alcohol patterns, resting heart rate and blood pressure, and morning blood cortisol and lipid levels. Assessment of a reference group of 40 non-hospital-exposed control participants was also conducted. RESULTS At the in-hospital assessment, study participants reported lower sleep time, altered 24-h physical activity patterns, reduced dietary and alcohol intake, and higher systolic and diastolic blood pressure than a nonhospitalised reference group. Compared to in-hospital assessment, these altered behavioural and physiological responses improved over time except for systolic blood pressures which remained unchanged at 3 months post family member discharge. CONCLUSION Hospitalisation is associated with altered behavioural and physiological responses in family members. These findings contribute to understanding of the impact of unexpected hospitalisation on family members' cardiovascular risk factors and provide insights into potential mechanisms for the proposed increased risk during this time. Elevated systolic blood pressure at 3 months post discharge suggests a prolonged cardiovascular stress response in many family members of critical care patients that requires further study, with a focus on contributing and potential modifiable factors.

Abstract
Introduction The abnormal hyperreactivity to food cues in individuals with binge eating behaviors could be regulated by hedonic or reward-based system, overriding the homeostatic system. The aim of the present study was to investigate whether attentional bias for food cues is affected by the level of hunger, maintaining the normal homeostatic system in individuals with binge eating behaviors. Methods A total of 116 female participants were recruited and divided into four groups: hungry-binge eating group (BE) (n = 29), satiated BE (n = 29), hungry-control (n = 29), satiated control (n = 29). While participants completed a free-viewing task on high or low-calorie food cues, visual attentional processes were recorded using an eye tracker. Results The results revealed that BE group showed longer initial fixation duration toward high-calorie food cues in both hunger and satiety condition in the early stage, whereas the control group showed longer initial fixation duration toward high-calorie food cues only in hunger conditions. Moreover, in the late stage, the BE group stared more at the high-calorie food cue, compared to control group regardless of hunger and satiety. Discussion The findings suggest that automatic attentional bias for food cues in individuals with binge eating behaviors occurred without purpose or awareness is not affected by the homeostatic system, while strategic attention is focused on high-calorie food. Therefore, the attentional processing of food cues in binge eating group is regulated by hedonic system rather than homeostatic system, leading to vulnerability to binge eating.

Abstract
In this study, we aimed to test the association of the Late Positive Potential (LPP) response and attachment dimensions in the choice of care/food pictures and its reaction time (RT) in threatening versus neutral conditions. Fifty-two participants (38 females, Mage 22.62) responded to the ECR questionnaire and were exposed to adequate visual stimuli, during EEG recording. Results showed that threatening stimuli increase the choice of care, decrease RT, and increase LPP magnitude in centro-parietal areas (Cpz, Pz, P3 and P4). Food choice was lower, with increased RT. Furthermore, larger LPP magnitude in centro-parietal cluster was associated with increased RT in the choice of care. Considering the dimensions of attachment, in threatening conditions, while anxiety was not associated with RT and care/food choice, avoidance was associated with an increase in care choice and RT. In conclusion, the specific association of increased RT in care choice with high LPP magnitude centro-parietal cluster may be explained in terms of a functional interference of these areas in the choice of care, but not of food. Further, we postulate that the increased RT of avoidant individuals may reflect a more articulated choice process.

Abstract
The primary aims of this study are to examine associations between obesity-related eating behaviors (OEB) and chronic and infectious diseases, and mental disorders. A representative nationwide survey was used to collect information among 11,659 medical students from 31 universities in China. Multiple variable logistic regression analysis was conducted to examine the associations between OEB and the diseases. The multiple variable logistic regression model found that OEB was significantly associated with chronic disease (OR (Odds Ratio): 1.74 < 95 % C.I (Confidence Interval): 1.45, 2.65 > ), infectious disease (OR: 3.37 < 95 % C.I: 1.04, 1.81 > ), and mental disorder (OR: 1.87(<95 % C.I: 1.55, 2.25 > ). These findings underscore the importance of addressing OEB in programs and policies to promote health and prevent disease among university students.

Abstract
People often engage in unhealthy eating despite having an explicit goal to follow a healthy diet, especially under certain conditions such as a lack of time. A promising explanation from the value accumulation account is that food choices are based on the sequential consideration of the values of multiple outcomes, such as health and taste outcomes. Unhealthy choices may result if taste is considered before health. We examined whether making a health outcome more salient could alter this order, thereby leading to more healthy choices even under time pressure. Two studies examined the time-dependent effect of outcome values and salience on food choices. Participants first completed priming trials on which they rated food items on healthiness (health condition), tastiness (taste condition), or both healthiness and tastiness (control condition). They then completed blocks of binary choice trials between healthy and tasty items. The available response time was manipulated continuously in Study 1 (N = 161) and categorically in Study 2 (N = 318). As predicted, results showed that the values of health and taste outcomes influenced choices and that priming led to more choices in line with the primed outcomes even when time was scarce. We did not obtain support for the prediction that the priming effect is time-dependent in the sense that primed outcomes are considered before non-primed outcomes. Together, these findings suggest that increasing the value and salience of a health outcome may be effective ways to increase healthy choices, even under poor conditions such as time pressure.

The Relationship between Social Anhedonia and Perceived Pleasure from Food-An Exploratory Investigation on a Consumer Segment with Depression and Anxiety. Foods 2022; 11:foods11223659. [PMID: 36429251 PMCID: PMC9689578 DOI: 10.3390/foods11223659] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2022] [Revised: 11/01/2022] [Accepted: 11/12/2022] [Indexed: 11/18/2022] Open
Abstract
Anhedonia, the diminished ability to experience pleasure, is a key symptom of a range of mental and neurobiological disorders and is associated with altered eating behavior. This research study investigated the concept of anhedonia in relation to mental disorders and the perception of pleasure from food to better understand the link between anhedonia and eating behavior. A consumer survey (n = 1051), including the Food Pleasure Scale, the Chapman Revised Social Anhedonia Scale, the Patient Health Questionnaire, and the Generalized Anxiety Disorder scale, was conducted to explore the perception of pleasure from food among people with anhedonic traits. Comparative analyses were performed between people with symptoms of depression and/or anxiety and people with no symptoms of these conditions. A segmentation analysis was furthermore performed based on three levels of anhedonia: Low, Intermediate and High anhedonia. Thus, insights into how food choice and eating habits may be affected by different levels of anhedonia are provided for the first time. Our findings showed that the 'Low anhedonia' segment found pleasure in all aspects of food pleasure, except for the aspect 'eating alone'. 'Eating alone' was, however, appreciated by the 'Intermediate anhedonia' and 'High anhedonia' segments. Both the 'Intermediate anhedonia' and 'High anhedonia' segments proved that their perceptions of food pleasure in general were affected by anhedonia, wherein the more complex aspects in particular, such as 'product information' and 'physical sensation', proved to be unrelated to food pleasure. For the 'High anhedonia' segment, the sensory modalities of food were also negatively associated with food pleasure, indicating that at this level of anhedonia the food itself is causing aversive sensations and expectations. Thus, valuable insights into the food pleasure profiles of people with different levels of anhedonia have been found for future research in the fields of mental illness, (food) anhedonia, and consumer behaviors.

Kim M, Kim Y. Psychosocial stress accompanied by an unhealthy eating behavior is associated with abdominal obesity in Korean adults: A community-based prospective cohort study. Front Nutr 2022; 9:949012. [PMID: 36245532 PMCID: PMC9561362 DOI: 10.3389/fnut.2022.949012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2022] [Accepted: 09/05/2022] [Indexed: 11/13/2022] Open
Abstract
Psychosocial stress is recognized as a potential modulator of eating behavior. Psychosocial stress also constitutes an independent risk factor for the development of non-communicable diseases. This study examined the gender-stratified associations between perceived stress, eating behavior, and abdominal obesity in 4,411 adults aged 40-69 years during a 10-year follow-up of the Korean Genome and Epidemiology Study (KoGES). Psychosocial stress was evaluated using the Psychosocial Wellbeing Index Short Form (PWI-SF), and eating behavior was analyzed with a focus on the dietary variety score (DVS). The Cox's proportional hazard model was used to examine the risk of abdominal obesity according to stress levels. Higher stress levels were associated with lower DVS in women. Lower DVS scores were positively associated with the consumption of grains and refined grains but was negatively associated with the consumption of fruits. The DVS was not significantly associated with stress levels among men. Prospectively, the highest tertile of grains and refined grains consumption showed an increased risk of abdominal obesity compared to the lowest tertile in women (HR: 1.36, 95% CI: 1.04-1.78, p < 0.05; HR: 1.28, 95% CI: 1.03-1.59, p < 0.05, respectively). By contrast, in all participants, the highest tertile of fruits consumption decreased the risk of abdominal obesity compared to the lowest tertile (men, HR: 0.56, 95% CI: 0.45-0.70, p < 0.01; women, HR: 0.51, 95% CI: 0.40-0.65, p < 0.01). Furthermore, high stress levels showed a borderline significant association with the risk of abdominal obesity only in women (HR: 1.27, 95% CI: 1.00-1.59, p < 0.05). These findings suggested that psychosocial stress might contribute to abdominal obesity by interacting with eating behavior represented by a low DVS. The approach to consume a diet with a high DVS might help decrease the risk of abdominal obesity among people in stressful environments.

Abstract
The study's objective was to determine the prevalence of food addiction (FA) in Brazilian university students and to verify whether there is an association with anxiety, depression, and adherence to the social distancing measures adopted during the COVID-19 pandemic. This is a nationwide cross-sectional study carried out through the application of online questionnaires. Self-reported data on age, sex, economic class, race/skin color, anthropometric data, depression diagnosis, anxiety, modified Yale Food Addiction Scale 2.0 (mYFAS 2.0), and adherence to social distancing measures were collected. 5368 participants were included, with a mean age was 24.1 ± 6.3 years, the majority were female (n = 3990; 74.3%), and the mean BMI in our sample was 24.5 ± 5.3 kg/m2. The prevalence of FA was 19.1% (95%CI: 18.0; 20.0%). An association was observed between FA with depression (PR: 1.60; 95%CI: 1.43; 1.78; p < 0.01), and anxiety (3.13; 95%CI: 2.74; 3.58; p < 0.01), but not with adherence to social distancing measures (p = 0.70). In conclusion, there was a higher prevalence of FA in Brazilian university students. Besides, university students with anxiety, depression, overweight, or obesity and females are more prone to FA.Level of evidence Level V, Opinions of authorities, based on descriptive studies, narrative reviews, clinical experience, or reports of expert committees.

Healthy versus unhealthy comfort eating for psychophysiological stress recovery in low-income Black and Latinx adults. Appetite 2022; 176:106140. [PMID: 35718313 DOI: 10.1016/j.appet.2022.106140] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2022] [Revised: 05/27/2022] [Accepted: 06/13/2022] [Indexed: 11/02/2022]
Abstract
Low-income Black and Latinx individuals are disproportionately vulnerable to chronic stress and metabolic disease. Evidence suggests that these populations engage in elevated levels of comfort eating (i.e., eating comforting food to alleviate stress), which can harm diet quality. For this reason, many interventions discourage comfort eating. However, if comfort eating does indeed buffer stress, it may be a protective health behavior, particularly if healthy foods (e.g., strawberries) buffer stress as effectively as traditional unhealthy comfort foods (e.g., brownies). By choosing healthy foods, people may be able to simultaneously improve their nutrition and reduce their stress levels, both of which have the potential to reduce health disparities among chronically stressed populations. The present study tested the efficacy of healthy and unhealthy comfort eating for improving psychophysiological stress recovery. A sample of low-income Black and Latinx individuals (N = 129) were randomly assigned to consume a healthy food (e.g., grapes), unhealthy comfort food (e.g., chips), or no food after exposure to a laboratory stressor. Throughout, we measured participants' psychophysiological stress responses, including self-reported stress, rumination, autonomic nervous system activation (i.e., electrodermal activity (EDA), heart rate variability (HRV)) and neuroendocrine responses (i.e., salivary cortisol). We compared participants' stress recovery trajectories by condition and found no significant group differences (p = 0.12 for self-reported stress; p = 0.92 for EDA; p = 0.22 for HRV, p = 1.00 for cortisol). Participants in all conditions showed decreases in self-reported stress and in cortisol post-stressor (ps < 0.01), but rates of decline did not differ by condition (i.e., healthy or unhealthy comfort food, brief no-food waiting period). Although null, these results are important because they challenge the widely-held assumption that comfort foods help people decrease stress.

Why Being 'Stressed' Is 'Desserts' in Reverse-The Effect of Acute Psychosocial Stress on Food Pleasure and Food Choice. Foods 2022; 11:foods11121756. [PMID: 35741954 PMCID: PMC9222595 DOI: 10.3390/foods11121756] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2022] [Revised: 06/10/2022] [Accepted: 06/10/2022] [Indexed: 12/04/2022] Open
Abstract
The link between acute stress, food pleasure and eating behavior in humans by employing measures of individual reward mechanisms has not been investigated as of yet. Having these insights is key to understanding why many people experience a change in eating behavior when experiencing stress. Thirty-five Danes (mean age 21.71 years) underwent a stress-inducing and relaxation-inducing task based on a randomized cross-over study design. Both tasks were combined with the Leeds Food Preference Questionnaire, to investigate the effect of stress on specific measures of food reward. Furthermore, participants chose a snack, as a covert measure of actual food choice. The study found no effect on explicit liking, explicit wanting or relative preference. For implicit wanting, an effect was detected on high-fat sweet foods, with increasing scores for the stress-induced condition. Moreover, 54% chose a different snack following the stress-inducing condition. Interestingly, 14% chose to change their snack choice to no snack at all. Results suggest acute psychosocial stress can increase cravings for highly palatable foods for some, while for others an experience of loss of appetite prevails. Overall, this study points to a further understanding of why consumers have issues with making healthy food choices, ultimately affecting public health too.

Abstract
Children typically prefer to attend to social stimuli (e.g. faces, smiles) over non-social stimuli (e.g. natural scene, household objects). This preference for social stimuli is believed to be an essential building block for later social skills and healthy social development. Preference for social stimuli are typically measured using either passive viewing or instrumental choice paradigms, but not both. Since these paradigms likely tap into different mechanisms, the current study addresses this gap by administering both of these paradigms on an overlapping sample. In this study, we use a preferential looking task and an instrumental choice task to measure preference for social stimuli in 3-9 year old typically developing children. Children spent longer looking at social stimuli in the preferential looking task but did not show a similar preference for social rewards on the instrumental choice task. Task performance in these two paradigms were not correlated. Social skills were found to be positively related to the preference for social rewards on the choice task. This study points to putatively different mechanisms underlying the preference for social stimuli, and highlights the importance of choice of paradigms in measuring this construct.

Abstract
This study examined effects of COVID-19 restrictions in early 2020 on movement (physical activity, sedentary behavior and sleep) and healthy eating behaviors in families with 0–12-year-old children in western Sydney, Australia. A total of 1,371 parents completed an online survey about changes in children's and families' food intake and movement behaviors. There was an increase in sedentary screen use by children (4.18/5.00) and families (3.91/5.00) and a slight increase in reported physical activity (3.56/5.00), amount of food consumed (3.58/5.00) and meals and snacks eaten (3.69/5.00) during the height of the COVID-19 restrictions compared to before. There was little change in reported sleep (3.17/5.00). Lower socioeconomic families were disproportionately affected, with greater increases in unhealthy eating (t = 2.739, P = 0.06), lower levels of improvement in physical activity, such as walking and cycling (t = −7.521, P < 0.001) and outdoor activity (t = 5.415, p < 0.001), and higher increases in family sedentary behavior (t = 2.313, P = 0.021). Therefore, even short periods of restrictions can result in detrimental health behavior changes. Such changes could become entrenched leading to increased risk of lifestyle diseases. Programmatic and policy strategies should be geared toward promoting healthy movement behaviors, focusing on families of lower socioeconomic status to ensure the pandemic does not widen an existing gap.

Abstract
Background Stressful situations can have an impact on an individual’s eating behavior. People vulnerable to the influence of stress tend to change the quantity and quality of their food intake. Variables such as sex and body mass index (BMI) seem to be related to this stress-eating behavior, but it is rather unclear what factors account to the parameters associated with stress-eating behavior. The aim of this survey was to identify further characteristics of adults in Germany related to stress-overeating, focusing on stress perception, coping, eating motives and comfort foods as well as personality types. Methods This online survey was performed throughout Germany and comprised a 38-item pre-tested questionnaire. Stress-induced overeating was classified based on the Salzburg Stress Eating Scale (SSES). Moreover, validated questionnaires were used to identify additional characteristics of stress eaters. Participants were recruited using a convenience sampling approach, and data were collected between January and April 2021. Results The overall sample consisted of 1222 participants (female 80.8%, aged 31.5±12.8). 42.1% of participants were identified as stress-overeaters. Among the remaining group, 78.9% stated to eat less, 21.1% to eat equally when stressed. Female participants had a higher mean SSES score compared to male participants. The BMI was positively correlated to SSES, r(1220)=0.28, p>0.005. ‘Agreeableness’ (BigFive) was found to be a negative predictor of stress-overeating. The most pronounced difference in eating motives (The Eating Motivation Survey, TEMS) was found for ‘Affect Regulation’ and ‘Weight Control’. Conclusions The results indicate that stress-overeating affects a large proportion of the surveyed population. BMI, personality and eating motives additionally characterize stress-overeaters and may contribute to develop new approaches to address unhealthy stress-related eating patterns.

Abstract
With shown reticence by men to engage with dietary interventions for weight loss, investigations that provide detail on men’s perceptions for the causes of weight gain and subsequent concerns over health and image are important. Such discoveries have potential to make a valuable contribution to male gendered programme design aimed at tackling weight gain and promoting good health. Connecting to men to health using their hobbies and interests, this study deployed semi-structured interviews of eight male participants (age > 35 years) enrolled on The Alpha Programme (TAP). TAP is a 12-week football and weight management intervention delivered in local community venues. Results captured men’s lived experiences and feelings of being overweight, their attempts at dietary modification, health and causes of weight gain. Results signify externalized attribution for weight gain, entrenched habitual intake practices, despondency related to weight stigmatization, self-objectification and low self-worth. Moreover, this study outlines the processes for capturing this information using a male friendly approach and setting. Outcomes have potential for shaping bespoke men’s weight management and health improvement interventions in the future.

Abstract
Stress leads to detrimental health outcomes through direct biological and indirect behavioural changes. Stress can lead to disruption to normal eating behaviours, although the strength of these associations is unknown. This is the first meta-analysis to determine the strength of the stress-eating relationship in healthy adults and to explore the impact of potential moderators. Studies included had a clearly defined measure of stress (i.e., any noxious event or episode in one's environment with the exclusion of emotional distress) that was linked to non-disordered eating. Key terms were searched in Medline, PsycInfo and Ovid databases (23,104 studies identified). 54 studies (combined N = 119,820) were retained in the meta-analysis. A small, positive effect size was found for the stress-overall food intake relationship (Hedges' g = 0.114). Stress was associated with increased consumption of unhealthy foods (Hedges' g = 0.116) but decreased consumption of healthy foods (Hedges' g = -0.111). Only one significant moderator (restraint on stress-unhealthy eating) was identified. This meta-analysis identified the magnitude of the effect of stress on eating behaviour outcomes. Significant heterogeneity was observed that was not explained by the moderators examined. Further research on moderators of the stress-eating relationship is required and should distinguish effects for healthy versus unhealthy eating.

Abstract
The relationship between stress and food consumption is complex and often characterised by substantial between- and within-person variation. From a theoretical and practical perspective, more research is needed to improve our understanding of the factors that influence this relationship. The aim of this study was to identify those factors, and to derive insight into the nature of their effects on the relationship between stress and food consumption. Using semi-structured interviews, 41 adult participants (M ± SD age = 26.7 ± 6.3 yr, BMI = 22.9 ± 3.0 kg/m2) were invited to reflect on their food consumption following stressor exposure, and to elaborate on the factors that influence stress-induced eating behaviour. Reflexive thematic analyses revealed insight into the different ways in which individuals respond to stress in terms of food quantity and choices, and more significantly, highlighted a range of factors that may influence stress-induced eating behaviours. These factors included the intensity and/or nature of the stressor, aspects of prioritisation, rewarding, knowledge of and perceptions about food, normative (e.g., family, friend) influences, automated or habituated behaviours, the availability of food, and selected coping mechanisms. These findings present important directions for researchers seeking to study the variation in stress-induced eating, and may hold substantial practical value by way of informing interventions designed to alleviate unhealthy dietary responses to stress.

The Nature and Extent of Online Marketing by Big Food and Big Alcohol During the COVID-19 Pandemic in Australia: Content Analysis Study. JMIR Public Health Surveill 2021; 7:e25202. [PMID: 33709935 PMCID: PMC7958974 DOI: 10.2196/25202] [Citation(s) in RCA: 21] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2020] [Revised: 11/29/2020] [Accepted: 12/16/2020] [Indexed: 12/16/2022] Open
Abstract
BACKGROUND Emerging evidence demonstrates that obesity is associated with a higher risk of COVID-19 morbidity and mortality. Excessive alcohol consumption and "comfort eating" as coping mechanisms during times of high stress have been shown to further exacerbate mental and physical ill-health. Global examples suggest that unhealthy food and alcohol brands and companies are using the COVID-19 pandemic to further market their products. However, there has been no systematic, in-depth analysis of how "Big Food" and "Big Alcohol" are capitalizing on the COVID-19 pandemic to market their products and brands. OBJECTIVE We aimed to quantify the extent and nature of online marketing by alcohol and unhealthy food and beverage companies during the COVID-19 pandemic in Australia. METHODS We conducted a content analysis of all COVID-19-related social media posts made by leading alcohol and unhealthy food and beverage brands (n=42) and their parent companies (n=12) over a 4-month period (February to May 2020) during the COVID-19 pandemic in Australia. RESULTS Nearly 80% of included brands and all parent companies posted content related to COVID-19 during the 4-month period. Quick service restaurants (QSRs), food and alcohol delivery companies, alcohol brands, and bottle shops were the most active in posting COVID-19-related content. The most common themes for COVID-19-related marketing were isolation activities and community support. Promotion of hygiene and home delivery was also common, particularly for QSRs and alcohol and food delivery companies. Parent companies were more likely to post about corporate social responsibility (CSR) initiatives, such as donations of money and products, and to offer health advice. CONCLUSIONS This is the first study to show that Big Food and Big Alcohol are incessantly marketing their products and brands on social media platforms using themes related to COVID-19, such as isolation activities and community support. Parent companies are frequently posting about CSR initiatives, such as donations of money and products, thereby creating a fertile environment to loosen current regulation or resist further industry regulation. "COVID-washing" by large alcohol brands, food and beverage brands, and their parent companies is both common and concerning. The need for comprehensive regulations to restrict unhealthy food and alcohol marketing, as recommended by the World Health Organization, is particularly acute in the COVID-19 context and is urgently required to "build back better" in a post-COVID-19 world.

Abstract
What if consumers are getting obese because eating less calories is more difficult for persons that have a higher pleasure and desire towards food (Ikeda et al., 2005) and food companies do not help given only a two extreme option choice to satisfy their needs (i.e., low calories vs. high calories or healthy vs. unhealthy)? Reward systems are being described with a new conceptual approach where liking—the pleasure derived from eating a given food—and wanting—motivational value, desire, or craving—can be seen as the significant forces guiding eating behavior. Our work shows that pleasure (liking), desire (wanting), and the interaction between them influence and are good predictors of food choice and food intake. Reward responses to food are closely linked to food choice, inducing to caloric overconsumption. Based on the responses given to a self-administered questionnaire measuring liking and wanting attitudes, we found three different segments named ‘Reward lovers,’ ‘Half epicurious,’ and ‘Non indulgents’. Their behavior when choosing food is quite different. Results show differential effects on caloric consumption depending on segments. The introduction of more food choices that try to balance their content is a win-win strategy for consumers, companies, and society.

Abstract
BACKGROUND Given previous research suggests an association between stress and the intake of energy-dense foods, this study investigated whether poststressor relaxation practice can attenuate stress-induced eating. METHODS Twenty-five men and women were exposed to four conditions on separate days: an acute laboratory stressor (S), acute stressor followed by 20 min of relaxation (SR) in the form of Abbreviated Progressive Muscle Relaxation (APMR), relaxation alone (R), and a control condition (C). Physiological and psychological responses to stress and relaxation were assessed, in addition to the subsequent energy intake of high-energy snacks. RESULTS Salivary cortisol, blood pressure, heart rate, and perceived stress were transiently elevated postlaboratory stressor (S and SR compared with R and C; p < .05). Meanwhile, perceived relaxation was acutely enhanced after APMR alone (R) compared with S, SR, and C (p < .05) and in SR (immediately after the APMR) compared with S (p < .05). No difference in mean energy intake was observed between conditions (p > .05). Likewise, no differences in perceived appetite or the levels of ghrelin, leptin, and insulin were found between conditions (p > .05). CONCLUSIONS Much variation exists in stress-induced dietary responses, and APMR either postacute stressor or in isolation does not appear to consistently alter the intake of commonly eaten snacks.

Abstract
BACKGROUND Stress is often associated with the intake of energy-dense palatable foods. This trial examined the feasibility and preliminary efficacy of an 8-week worksite-based relaxation intervention to address psychological stress and unhealthy food intake. METHODS Thirty-six men and women were exposed to an acute stressor, while physiological and psychological responses were assessed, prior to being offered a test meal. Participants were then randomised to a relaxation intervention (RELAX; face-to-face classes and daily home practice of progressive muscle relaxation and mindfulness meditation), or a wait-list control (CON). All measures were repeated after the intervention. RESULTS Intervention compliance was high (80% ± 19% face-to-face; 79% ± 18% home practice), and each session acutely reduced perceived stress (p < .001) and increased relaxation (p < .001). After 8 weeks, trait mindfulness was increased (p = .025), along with reduced tension (p = .013) and increased relaxation (p < .05) post-acute stressor in the intervention group. There was no effect of the intervention on palatable eating, cravings, or energy intake at a laboratory test meal, with small associated effect sizes (d = 0.01-0.3). CONCLUSIONS The program studied here is feasible and sessions transiently reduce perceived stress and improve mindfulness; however, the program may not influence the physiological response to an acute stressor or appetite and eating variables.

Abstract
Medication errors can have deleterious effects on patient safety and care. Interruptions, patient acuity and time pressures have all been cited as contributing factors in the incidence of medication errors. Yet, despite the number of different strategies that can be taken to reduce the incidence of medication errors, they still occur. The strategies often focus on refining systems and processes, depending on the root cause of the error. However, less recognised as contributory elements are human factors such as anger, hunger or tiredness. The aim of this quality improvement initiative was to reduce medication errors by 25% on a medical ward, through the introduction of the hunger, angry, lonely, tired (HALT) model to address the human factors associated with medication errors. Post-implementation, the HALT model appeared to have resulted in a total reduction in medication errors over a 2-month period by 31%. Mistakes related to human error were reduced by 25%, and those linked to communication and documentation errors by 22%. While this was a small-scale study, this is a significant reduction in medication errors. However, caution should be used when addressing other contributing factors associated with medication errors as using HALT alone will not address these.

Is comfort food actually comforting for emotional eaters? A (moderated) mediation analysis. Physiol Behav 2019; 211:112671.

Abstract
An important but unreplicated earlier finding on comfort eating was that the association between food intake and immediate mood improvement appeared to be mediated by the palatability of the food, and that this effect was more pronounced for high than for low emotional eaters [26]. This has not yet been formally tested using mediation and moderated mediation analysis. We conducted these analyses using data from two experiments on non-obese female students (n = 29 and n = 74). Mood and eating satisfaction in Study 1, and mood, tastiness and emotional eating in Study 2 were all self-reported. In Study 1, using a sad mood induction procedure, emotional eaters ate more food, and when mood was assessed immediately after food intake, 'eating satisfaction' acted as mediator between food intake and mood improvement (decrease in sadness or increase in happiness). In Study 2, where we measured the difference in actual food intake after a control or a stress task (modified Trier Social Stress Test), and assessed mood during the food intake after stress, we found significant moderated mediation. As expected, there was a significant positive mediation effect of tastiness between food intake and mood improvement in the high emotional eaters, but also a significant negative mediation effect of tastiness between food intake and mood improvement in the low emotional eaters. This suggests that tastiness promotes 'comfort' from food in female emotional eaters, but conflicts in non-emotional eaters with a tendency to eat less when stressed. In conclusion, palatable food may indeed provide comfort specifically for high emotional eaters during eating.

Abstract
Work and employment are important elements of every working person’s life. If an employee loses his or her job, he or she loses an important and determining part of his or her life. To reduce the negative effects that affect the quality of an employee’s life, outplacement programs were established as a part of sustainable human resource management. Sustainable human resource management emphasises the importance of employee care. Outplacement, for its part, includes support for employees at their last stage in the organization. The main aims of the paper are to present the research results focused on the perceived usefulness of outplacement programs for dismissed employees, to analyse the relationships between the emotions felt by redundancies and other employees as well as the comparison of differences in emotions felt by different generations of dismissed employees. A valid collection tool (research questionnaire) was developed for research purposes and distributed to employees of industrial enterprises in the Slovak Republic. Overall, the research set was composed of n = 692 employees from different generational groups. The research results proved the existence of a relationships between the emotions felt by redundancies and other employees and differences in emotions felt by employees from different generational groups.

Mood and appetite: Their relationship with discretionary and total daily energy intake. Physiol Behav 2019; 207:122-131.

Abstract
BACKGROUND Negative affect is shown consistently to promote unhealthy food choices and dietary intake in laboratory studies. However, this relationship in naturalistic settings is less clear and previous research is limited by dietary assessment methodology and neglects to account for several important moderating variables. This observational study aimed to examine the association of negative affect and other psychological factors associated with eating behaviour simultaneously with discretionary energy intake and total energy intake, and whether these were moderated by emotional eating predisposition or age, sex and weight status. METHODS One hundred adults completed a four-day food diary, a concurrent end-of-day questionnaire that assessed daily affect and experience of appetite, and the Three Factor Eating Questionnaire to assess trait eating behaviour. Food diaries provided data on participants' daily intake of total energy and of "discretionary items" (specific energy-dense and nutrient poor foods and beverages as defined by the Australian Guide to Healthy Eating). Stepwise random effects models were used to estimate the association of end-of-day ratings, trait eating behaviour and personal factors, and their interactions, with discretionary and total energy intake. RESULTS Daily rated negative affect and appetite were significantly and positively associated with discretionary intake, such that a one unit increase in each scale was associated with eating 139 kJ/d [SE 61] and 194 kJ/d [SE 68] more discretionary energy, respectively. Negative affect and its interaction with emotional eating were consistently, positively associated with discretionary energy intake. This relationship was strongest in younger participants (β = -4.9 [SE 2.2], p < .05). There was no interaction with sex or weight status. Total energy intake was not associated with negative affect nor its interaction with emotional eating but was consistently associated with appetite. CONCLUSION When personal factors (age, sex, BMI), trait eating behaviours and daily rated negative affect and appetite are considered simultaneously, daily discretionary intake is associated most strongly with negative affect. Individuals, particularly young adults, may be more likely to overeat discretionary energy on days that negative affect is rated more highly. However, this may not necessarily translate into greater total energy intake which was most consistently associated with daily rated appetite.

Abstract
Introduction: Binging is the consumption of larger amounts of food in a briefer period of time than would normally be consumed under similar circumstances. Binging requires palatable food (PF) to trigger abnormal eating, probably reflecting gene × environment interactions. In this study we examined the impact of trait binge eating (BE) and its compulsive nature on the conflict between hedonic eating of PF and anticipation of a delayed aversive effect. We used female rats as an animal model similar to other models of BE. A novel aspect of this model in this paper is the use of a delayed internal aversive effect produced by lactose ingestion. Establishing this model will allow us to better understand the nature of the conflict between immediate reward and its delayed aversive implications. We hypothesized that BE prone (BEP) rats will demonstrate maladaptive decision making, presenting higher motivation toward PF even when this is associated with delayed discomfort. Method: (Phase 1) 52 female adult Wistar rats were divided to two eating profiles: resistant and prone binge eaters (BER/BEP) based on intake of liquid PF (Ensure). Next, all subjects underwent a Lactose Conditioning Protocol (LCP) that included 4 h tests, one baseline and 3 conditioning days (Phase 2), in which solid PF (Oreo cookies) was paired with glucose (control-no internal aversive effect) or lactose, dissolved in liquid PF. Index for PF motivation was PF consumption during the 4 h LCP. To test for memory of lactose conditioning, we performed another LCP with glucose only (anticipation, but no actual lactose-induced discomfort), a week after the last conditioning session. Results: Lactose conditioned BEP showed higher motivation toward PF compared to lactose conditioned BER faced with delayed aversive effects. Only lactose conditioned BER rats devaluated the PF over LCP days, indicating an association between PF and abdominal discomfort. In addition, only lactose conditioned BER presented an adaptive dynamic behavior, by varying PF intake according to consequences. Furthermore, solid PF consumption was predicted by binge size of liquid PF, only for lactose conditioned rats. Conclusions: We established an animal model for a common eating conflict in humans using delayed internal aversive unconditional stimuli.

Abstract
The anterior medial temporal lobes are one of the most studied parts of the brain. Classically, their two main structures - the amygdalae and the hippocampi - have been linked to key cognitive and affective functions, related in particular to learning and memory. Based on abundant evidence, we will argue for an alternative but complementary point of view: they may also play a major role in food intake and body weight regulation. First, an overview is given of early clinical evidence in this line of thought. Subsequently, empirical evidence is presented on how food intake, including in the extreme case of obesity, may relate to amygdalian and hippocampal functioning. The focus is on the amygdala's role in processing the relevance of food stimuli, cue-induced feeding, and stress-induced eating and on the hippocampus' involvement in the use of interoceptive signals of hunger and satiety, as well as memory and inhibitory processes related to food intake. Additionally, an elaboration takes place on possible reciprocal links between food intake, body weight, and amygdala and hippocampus functioning. Finally, issues that seemed particularly critical for future research in the field are discussed.
